ROD-PACKING.

SPECIFICATION forming part of LettersPatent No. 594,119, dated November 23, 1897. Application filed April 7, 1897. Serial No. 631,046. (No model.)

To 00% whom it may concern:

Be it known that we, ALFRED W. MORRIS, a subject of the Queen of Great Britain, and ALFRED D. MoRRIs, a citizen of the United States, both residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Rod-Packing, which improvement is fully set forth in the following specification and accompanying drawings.

Our invention consists of an improved construction of rod-packing, the same embodying a sectional T-shaped ring having located on the sides thereof polygonal and angularshaped sectional rings, respectively, whereby a better and more eflt'ective packing is produced than heretofore.

It further consists of novel details of construction, all as Will be hereinafter fully set forth, and specifically pointed out in the claims.

Figure 1 represents a perspective view of rod-packing embodying our invention. Fig. 2 represents a longitudinal sectional view of Fig. 1. Fig. 3 represents a perspective View of a portion of the packing in detached position.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates packing in assembled position, the samebeing retained by an inclosing casing, the same consisting of a plate B, which has an annular groove 0 therein, said groove being engaged by the shell D, which is provided with the intermediate inwardly-extending flange E, the extremity of said shell being covered by the plate S, which is adapted to contact with a cylinder, (not shown,) the opening in said plate S for the passage of the piston-rod T being of course slightly larger than the latter.

F designates the body of the packing proper,

the same consisting of a T-shaped ring H, the latter being provided with a web G and laterally extending or overhanging walls J, said walls being provided with a peripheral groove or grooves K, in which the coil or other shaped springs L are located, two grooves being in the present instance employed.

M designates pins on the sides of the Web G, against which the extremities of the se mental sections or rings N and R are adapted to abut Wh en the parts are assembled, said section N being of annular shapeand provided with the portion P, which contacts with the web G and the lateral or overhanging wall J, while the flange or lug Q contacts with said wall alone, it being noted that said flange Q by reason of its novel location relative to the contiguous wall J serves an important function in breaking the joint between the section N and the ring I-I, thereby preventing the egress of steam into the engine-room during the reciprocation of the piston.

The packing-ringRis made in the present instance substantially rectangular in crosssection and is seated in the space between the web G and the overhanging wall J opposite to the ring N.

It will be noted that in each instance the body or T-shaped ring F is made in sections or segments, preferably three in number, while the rings N and R are also made in sections, preferably three I in number, the whole being assembled in staggered order, so as to break joints in the manner indicated.

The operation is as follows: The parts are placed in position upon the piston-rod in the order indicated in Fig. 2, the plate S contactin g with the face of the cylinder, (not shown the sections R and N of the segmental rings being located on either side of the web G of the T-shaped ring F, as indicated in Fig. 2,

and being held between the plate Sand the flange E, it being noted that the joints are arranged in staggered order, so that there is no possibility of leakage of steam, the springs L also assisting to hold the various sections in juxtaposition. The parts are held in assembled position by the passage of studs secured in the cylinder (not shown) through openings in the plate B, the latter being held by means of the nuts on said studs in the usual manner.

It will of course be evident that instead of employing a plurality of T-shaped rings, as seen in Fig. 2, a single T-shaped ring and the segmental rings N R on either side thereof may be employed, as seen in Fig. 3, the function and operation of the parts being the same as already described. It will be seen that the function of the pin or pins M is to posibut a single set of springs L may be employed, if desired.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A packing consisting ota sectional T- shaped ring having a projecting web and laterally-extending Walls, means for holding the sections of said ring in juxtaposition, substantially rectangular sectional rings located on one side of said web, and angular-shaped sectional rings located on the other side of said web, said angular rings having a flange engaging the contiguous laterally-extendingwall of said T-shaped ring, whereby leakage of steam is prevented.

2. A packing consisting of a T-shaped ring having a projecting web and laterally-extending walls, a groove or grooves in said ring, springs located in said grooves, substantially rectangular-shaped sectional rings located on one side of said web, and angular-sl1aped sectional rings located on the other side of said web, said angular rings having a flange engaging the contiguous laterally-extending wall of said T-shaped ring, whereby leakage of steam is prevented.

3. In a packing, a T-shaped ring having a depending web,and laterally-extending walls, a groove 0r grooves in said ring, springs located in said grooves, pins located in said web, substantially rectangular sectional rings located on one side of said web, and angularshaped sectional rings located on the other side of said web, said angular rings having a flange engaging the contiguous laterally-extending wall of said T-shaped ring.

4. In a packing, the plates S and B, the shell D supported thereon and provided with an inwardly-extending flange E,T-shaped sectional rings H having inwardly-extending webs and laterally-extending walls, saidrings being located in the spaces between said plates and flange, rectangular rings R located in proximity to a side of said webs, angularshaped rings N located between one of said webs and the flange E and also between the other of said webs and the plate 13, respectively, and means for holding said rings and their adjuncts in juxtaposition.
